To ((17 who/1t it may concern:

Be it known that 1, WILLIAM RICHARD CLAY, a subject of the Queen ofGreat Britain, residing at Slater Street, Farnworth, near Bolton,Lancaster county, England, have invented a new and useful Improvement inBurners for Incandescent Gas-Lighting, of which the followingis aspecification.

In connection with incandescent gas-light-' ing much inconvenience andloss are experien ced and entailed by reason of the excessive delicacy,fragility, or brittleness of the incandescent substances orarticles'produced out of them, for which reason street or like publiclighting by these incandescent means has heretofore been attended withthe greatest difficulties, since often the vibrations of the burner,caused by a passing vehicle, have been sufficient to completely destroythe'iuseful properties of the incandescent article, causing it to breakaway in pieces or even to fall to dust. Again, it has been found to addgreatly to the efficiency of the combustible gas, provided it is fed tothe flame at a high temperature, while further, as is well known, theloose edges of the incandescent articles, which are in an ordinary wayentirely exposed to the friction of the currents of air flowing tosupport combustion, deteriorate, and portions of them are broken offlong prior to the other parts of said articles being worn out. Toobviate these difficulties by the application of means for counteractingor otherwise changing the nature of the vibratory motions of the burnersand for enabling the heat of the flame to be transmitted or imparted toor utilized for heating the combustible gas as it is being fed to theflame, as well as by the application of means for protecting the looseedges of the incandescent articles, is the object of this invention, andthis object I attain by the means hereinafter described, the same beingillustrated by the accompanying sheets of drawings, in which- Figure 1is an elevation of an ordinary streetlamp, shown as with a portion ofthe lantern or cover cut away in order that my improved burner mightbemore clearly illustrated within it. Fig. 2 is an elevation showing myimproved burner in one of its simplest forms. Fig. 3 is a similarelevation to Fig. 2, but shows the manner in which a shade and cover maybe applied in connection therewith. Fig. elillustrates a method wherebya single suspended pipe may supply gas to more than one of my improvedburners. Figs. 5 and 6 are side and edge views, drawn to an enlargedscale, of a parthereinafter described. Fig. '7 is an elevationillustrative of a method whereby several of my improved burners may bearranged to be fed and supported by a single supply-pipe extendingvertically. Fig. 8 is an elevation showing an arrangement of suspendingmy improved burner where the use of the heat from the flame is not soextensi vely employed for heating the combustible gas fed thereto. Figs.9, 10, and 11 are elevations illustrating methods of mounting myimproved burner that I employ when the heating of the combustible gas tobe supplied thereto is not desired. Figs. 1.2 and 13 are an elevationand a section of the shield or cover for protecting the incandescentarticle.

Similar letters of reference indicate similar parts throughout theseveral views.

In carrying my invention into efiect I make a portion b of the pipewhich conducts gas to the burner a integral with or as part of saidburner a, and this part b of the supply-pipe, which I make of anappropriately coiled or spiral form, answers or is used at all times asthe support for the burner to and the incandescent article c, and sincethe said coiled or spiral formation brings the supporting part 1) intosuch a condition as to make it have considerable resilience the partssupported by it are protected against the damaging effects of thevibratory movements of adjoining bodies, for the reason that all suchmovements have to traverse this resilient supporting-pipe prior toreaching the parts it supports. Hence those of the said vibratorymovements which are not entirely lost in the said resilience of the partb are so far checked by it as to have their jerky or sudden changes ofdirection so altered as to reduce their clamaging actions on the article0 to a minimum.

No particular material is necessary out of which to make thesupply-pipe, but this is regulated as is also the size of the pipe andof the coils by the kind of burner employed. Ordinary gas-piping wouldanswer very well for very large burners, provided very large coils wereformed, while smaller burners, as

. gas supplied to it through the part b, the coiling of this part bisarranged to be above and about the incandescent article 0, as shown byFigs. 1, 2, 3, 4, and 7.

A simple form of coiling the part b is shown by Figs. 1 and 2, while inFig. 3 a method is shown whereby a shade or deflector e and cover fmight be supported by the part b, or several of the simple forms ofcoiled parts I) may be arranged to be supported by a central supply-pipeg, as shown by Fig. 4. Again, one coiled part b may be formed integrallywith several burners a, as shown by Fig. 7,

since in this as well as in all the foregoing cases the counteractingproperties of the said resilient partb are brought fully into use, whilethe position it occupies enables the heat from the flame to betransmitted to the gas being-fed thereto. Further, where the heating ofthe gas is not to be considered then the part-b may be either above theburner a, as shown by Fig. 8, or below same, as shown by Figs. 9, 10,and 11, and whenever desired by-pass pipes it may be arranged with theseburners, as shown by Figs. 1 and 4, in order to supply gas to a smallflame for igniting purposes as occasion or necessity may require or showto be desirable.

To protect the lower edges of the incandescent articles c, I form ametal shield 70 to encircle the outer edge of said article 0, as shownby Fig. 12, as also to fit as tightly as convenient against thecylindrical part m of the burner a, while the lower edge 7c of theshield 7.; opens out to somewhat bell-mouth shape in order that it mayrest upon the part 11, which supports the chimney p, ventilating-holes10 being made in the shield is to allow the air to flow freely to theflame.

Under most circumstances it is found that the lower edges of the articlea deteriorate more quickly than any other parts of them. Hence it isdesirable to lower these articles as they thus wear away, so that theywill be brought into the most desirable part of the flame. To accomplishthis, I make the central support .9 to have a series of hooks 8extending vertically, as shown by Figs. .5 and 6, so that the supportingor cross piece of the article a may be made to take over one or other ofthese hooks s as itsposition may be most appropriate.

Such being the nature and object of my invention, what I claim is l. Thecombination with a burner for incandescent gas-lighting, of a gas-supplypipe wholly supporting said burner and coiled to provide resiliency andabsorb vibration, sub stantially as described.

2. 'lhecombinat-ion with the parts forming an incandescent gas-burner ofa spiral, or coiled resilient supply-pipe for supporting the other partsforming said burner, said supply-pipe being coiled around or arrangednear the flame of the said burner substantially as and for the purposesspecified.

3. The combination with an incandescent gas-burner of a fixedsupporting-piece having a vertical series of hooks for holding theincandescent article or part of said burner substantially as hereinspecified.

XVILLIAM RICHARD CLAY.
